Hi @Steve.Kada !
Every user can log in to the Deezer by entering an email address and
that is quick way to check if you have an email address associated with a Deezer account .
From Deezer Help center :
iOS Android
- On the Welcome page, enter an email address
- Select
- If you are taken to the Create a password page, you do not have a Deezer account associated with that email address
If you are taken to the Your password page, you do have a Deezer account associated with that email address
"I don't remember my password"
Whether you've forgotten your email, your password or both you can find your account and reset your password with these steps:
- Go to our password reset form
- Enter your email address. If you have multiple email accounts and are unsure which is the one linked to your Deezer account, enter all of your email addresses
You will receive a password reset email from Deezer
- Select the link within the email to reset your password
Note: When your password is successfully updated, you will see a message on the screen
After you find the account, Admin can add it to Family again.
